I usually recommend IBM Instana Observability for companies in the academic environment, as I have been working in a consultancy company for the last three years, where one of our customers built teaching environments with many connections. I cannot remember the name, but it is in the academic space.
Additionally, I have presented the features and characteristics of IBM Instana Observability to many customers here in Spain, including BBVA, Consum, a retail company, and Telefónica. My role involved presentations and proof of concepts rather than installation and operation. With the academic-oriented company, I solved some problems related to installation, configuration, and recommendations.
Using IBM Instana Observability for non-distributed applications does not seem sensible because if an application is housed on a single server, it falls under traditional monitoring systems where you simply check CPU, storage, I/O, and memory. For that, you do not need IBM Instana Observability. The real strength of IBM Instana Observability lies in observing distributed applications, identifying where failures happen across services interconnected on multiple servers.
